I've always owned and ridden MX bikes but from my high school days I always liked the looks and sound of the DT2s and DT250s. So when the opportunity recently came along to pick up a DT2 to restore I jumped on it. Great looking bike but I have to say I was pretty disappointed with the lack of power compared to a MX bike so I started researching how to wake this thing up. In my search I came across a thread about Dave Meis modifying the stock pipes with good results, so off came the pipe and I shipped it off to Dave

I got my pipe back from Dave today and reinstalled it. I must say I'm very impressed with the improvement. It's still not the power of a modern MX but a very noticeable improvement. It's actually fun to ride now! Just a tad bit louder than stock but not obnoxious. It has no problem going into the red line now and the front wheel feels much lighter. Highly recommended mod that retains the stock look. Excellent work Dave . Thank You!

Bottom line: I'm very happy!

Dave does great work, and his pipes give a noticeable improvement. Welcome to the sleeper club!

I agree completely and almost word for word on my assessment of my DT400C after the sleeper pipe was fitted.

Amazingly my CT3 175 feels faster and definately snappier than my DT2. Would love to wake my DT2 up.

Not so amazing...  the 175's have roughly the same power to weight ratio as the 250. I find the smaller 175 a lot more fun to ride...  with the exception of modern day traffic...  the bigger bikes are better on the highways. 

I'm a little fuzzy on the exact details like year but I believe Larry Shoemaker from International Cycle in California won the 250 national championship in the early 1970's...  on a Yamaha CT 175!!!

I have two pipes that were done by Dave (and I think he may have had a partner at the time)
He does wonders with the old pipes.  Great work.
However... Hooka-2, you must be deaf!  LOL

RT1: Not totally deaf but been riding 2 stroke jet skis for the last 20 years. Maybe that explains it
 

And dave meis contact is?

I think that might be his username as well, so maybe try messaging him (big green button, top right). Be patient, though - messaging function here is a tad slow!

There's a whole massive thread Dave started....  here's a link to what I think is the most recent price list.  His contact info is repeated several times in the thread.
